A taxonomy and comparison of remote voting schemes

Remote voting has been an active research field for application of cryptographic techniques in the last two decades with many schemes and systems in publication. In this paper we present an overview of recent efforts in developing voting schemes and security models that involve a variety of real world constraints to ensure election integrity. We classify voting schemes based on their primary cryptographic techniques. We analyze recent typical schemes and systems against the basic and counter attack requirements with brief description. Such analysis shows difference among these security requirements and aids in design of future schemes. Our conclusion is provided regarding suitability of a particular voting system/scheme under various conditions.
